Not the camps. The reeducation. POst 1975 there hundreds of thousands sent for reeducation, from the lowliest private to flight officers to government officials. Now it is a far smaller number.
I know of several Vietnam era officers who have been released post-1995, and of another civilian publisher who was released from jail only a couple years ago (he was incarcerated right after 1975).
That is good to here. Are you going to visit someday?
